Quotes on Observation

The philosophical question before us is, when we make an observation of our track in the past, does the result of our observation become real in the same sense that the final state would be defined if an outside observer were to make the observation?

Things of which there is sight, hearing, apprehension, these I prefer.

Naturalists, like poets, are born and then made only by years of painstaking observation.

None of the miracles with which ancient histories are filled, occurred under scientific conditions. Observation never once contradicted, teaches us that miracles occur only in periods and countries in which they are believed in and before persons disposed to believe in them.

Almost all the greatest discoveries in astronomy have resulted from what we have elsewhere termed Residual Phenomena, of a qualitative or numerical kind, of such portions of the numerical or quantitative results of observation as remain outstanding and unaccounted for, after subducting and allowing for all that would result from the strict application of known principles.

Observation of my life to date shows that the larger the number for whom I work, the more positively effective I become. Thus, it is obvious that if I work always and only for all humanity, I will be optimally effective.

First, it is necessary to study the facts, to multiply the number of observations, and then later to search for formulas that connect them so as thus to discern the particular laws governing a certain class of phenomena. In general, it is not until after these particular laws have been established that one can expect to discover and articulate the more general laws that complete theories by bringing a multitude of apparently very diverse phenomena together under a single governing principle.

At the last dim horizon, we search among ghostly errors of observations for landmarks that are scarcely more substantial. The search will continue. The urge is older than history. It is not satisfied and it will not be oppressed.

It is a misfortune for a science to be born too late when the means of observation have become too perfect. That is what is happening at this moment with respect to physical chemistry; the founders are hampered in their general grasp by third and fourth decimal places.

An independant reality in the ordinary physical sense can neither be ascribed to the phenomenon nor to the agencies of observation.

Magnitude may be compared to the power output in kilowatts of a [radio] broadcasting station; local intensity, on the Mercalli or similar scale, is then comparable to the signal strength noted on a receiver at a given locality. Intensity, like signal strength, will generally fall off with distance from the source; it will also depend on local conditions at the point of observation, and to some extent on the conditions along the path from source to that point.

To command their professors of astronomy to refute their own observations is to command them not to see what they do see and not to understand what they do understand.

Association with human beings lures one into self-observation.

So far as love or affection is concerned, psychologists have failed in their mission. The little we know about love does not transcend simple observation, and the little we write about it has been written better by poets and novelists.

[The internet] ought to be like clay, rather than a sculpture that you observe from a distance.

Well-established theories collapse under the weight of new facts and observations which cannot be explained, and then accumulate to the point where the once useful theory is clearly obsolete.

The drawings don't start with 'a beautiful mark'. It has to be a mark of something out there in the world. It doesn't have to be an accurate drawing, but it has to stand for an observation, not something that is abstract, like an emotion.

I am not accustomed to saying anything with certainty after only one or two observations.

In the beginning there were only probabilities. The universe could only come into existence if someone observed it. It does not matter that the observers turned up several billion years later. The universe exists because we are aware of it.

Whoever wishes to acquire a deep acquaintance with Nature must observe that there are analogies which connect whole branches of science in a parallel manner, and enable us to infer of one class of phenomena what we know of another. It has thus happened on several occasions that the discovery of an unsuspected analogy between two branches of knowledge has been the starting point for a rapid course of discovery.

It is impossible for us, who live in the latter ages of the world, to make observations in criticism, morality, or in any art or science, which have not been touched upon by others. We have little else left us but to represent the common sense of mankind in more strong, more beautiful, or more uncommon lights.
